c# - How to access parameters sent from iframe in ASP.Net?

Question

I am working on a web application project in ASP.Net and I have two separate pages: In the first page Default.aspx, I am using the iframe to call the second page Test.aspx. I passed two parameters in the src attribute of iframe.

<iframe src="Test.aspx?Param1=<%=var1%>&Param2=<%=var2%>" 
scrolling="no" width="100" height="275px" frameborder="0"></iframe>

The question is how to access Param1 or Param2 in the Test.aspx page.
Thanks in advance

Answer 1

They should be available as Param1 and Param2 in the QueryString property of the request in Test.aspx, in the form Request.QueryString["Param1"] and must already be present as var1 and var2 in the parent Default.aspx
